APPARATUS FOR MAKING GAS.

SPECIFICATION forming part of Letters Patent No. 600,221, dated March 8,1898.

Application tiled April 19, 1897. Serial No. 632,783. (No model.)Patented in England April 1B, 1896, No. 8,239, and in Germany April 25,1896, No. 55,740.

To all whom it may concern.-

Be it known that I, ERNST GREY, a subject of the Emperor of Germany,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Apparatus for the Manufacture of Illuminating-Gas, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming a partthereof, and for which Letters Patent were granted in Great Britain, No.8,239, April 18, lQG, and in Germany, No. 55,740, April 25, 1 96.

My invention has relation to improvements in apparatus for manufacturingilluminatinggas; and it consists in the novel arrangement andcombination of parts more fully set forth in the specication and pointedout in the claim.

In the drawings, Figure 1 is a middle vertical sectional elevation ofthe apparatus, showing the air-pump in elevation. Fig. 2 is a section online rc of Fig. 1, and Fig. 3 is a section on line y y of Fig. 1.

The object of my invention :is to construct an apparatus wherein liquidhydrocarbons can be readily treated in connection with air at ordinarytemperatures for purposes of producing illuminating-gas.

In detail the apparatus may be described as follows:

Referring to the drawings, 1 represents an air-pump mounted on asuitable base 2 and operated from any suitable source of energy, buthere shown as operated by an explosiveengine 3, fed by the gas generatedby the apparatus. Leading from the air-pump is a pipe a, provided with avalve or cock 5, the said pipe passing through the lower portion of thewall of the water-tank 6 and projecting a suitable distance above thewater-level in said tank and into the pneumatic oat 7, confined withinthe peripheral walls of the tank, the said float being provided with aninner depending rod 8, operating within a tube 9, projecting from thebase of the tank, whereby the float is guided in its movements withinthe tank.

The float 7 is also provided with an air-escape pipe 10, extendingnormally to a slight distance below the level of the Water in the tank 6and extending outwardly through the upper Wall of the iioat, the objectof said air-pipe being to allow for the escape of the excess of airforced under the iioat, such escape taking place when the lower edge ofthe oat approaches too near to the surface of the water in the tank. Theupper end of the pipe 10 is provided with a chamber 11, having openings12 in the walls thereof for the escape of the said excess of air, andhaving a deiiector 13 for returning any water to the tank which may bemechanically carried up by the upward rush of air through the pipe 10.Leading also from the tank 6 and disposed similarly to the pipe Llis apipe 14C, provided with a controlling-valve 15, the free end of the saidpipe being provided With a horizontal extension 14', having a series ofopenings 16 disposed along the upper peripheral wall thereof. Theextension 14 is disposed along the base of the inner surface of areceptacle 17, designed to receive from a suitable supply vessel18liquid hydrocarbon-such as ligroin, naphtha, and the like-the saidhydrocarbon being admitted through a pipe 19, communicating with thelbottom and one end of the vessel 18 and receptacle 17, respectively. Thereceptacle 17 is provided with a gage 19 and drip-valve 20.

To equalize the pressure between the vessel 18 and receptacle 17, lestablish communica tion between the upper parts of the interiors of thevessels by a pipe 21, controlled by a valve 22. Leading from acollecting-dome 23 on the upper peripheral Wall of the receptacle 17 isa pipe 24, provided with a valve 25, below which there extends a pipe 26to any suitable burner or burners, (not sl1own,) or, as in the presentcase, to the explosive-engine, by which the airpump 1 is operated. Tobetter introduce the hydrocarbon into the vessel 18, I provide thelatter with a funnel 27.

Normally the extension 14: is submerged below the level of thehydrocarbon admitted into the receptacle A17. The air-pump forces theair under the oat 7, the weight of the latterpausing a constant pressureof air to escape through the openings 16 of the pipe 14', the air thusforced through the openings absorbing the volatile constituents from theliquid hydrocarbon within which the pipe is submerged. The mixture ofair and said volatile constituents constitutes the illumiynating-gas,which gas is delivered through the pipe 19 provided with valves 28 29,the former beingva general valve which may always remain open and thelatter a regulatingvalve which may to a nicety control the escape of theliquid from the Vessel 18 to the receptacle 17.

Having described my invention, what I claim is y ln combination with acarbureting system, a water-tank, a ioat movable therein, an escape-pipecarried by the float, the lower end thereof being normally closed by thewater in the tank, but arising above the Water-level on an excess ofpressure in the float, a chamber having perforated walls located at theupper end of the said pipe, and a delector located within the saidchamber below the perforations therein to prevent the escape of waterthrough the pipe, substantially as described.

In testimony whereof Iafx my signature in presence of two Witnesses.l
